MQ-131 Ozone Gas Detector Sensor Module
Description:
MQ-131 Ozone Gas Sensor Module is a highly sensitive semiconductor sensor designed specifically for detecting ozone (O₃) gas concentrations in the air. Ozone is a highly reactive gas that can be harmful to human health at certain levels. The MQ-131 sensor module is widely used in air quality monitoring systems, environmental safety devices, and industrial applications to detect and control ozone levels.Sensor uses tin dioxide (SnO₂) as its sensitive material, whose resistance changes in response to the presence of ozone gas. The MQ-131 sensor provides both analog and digital outputs, making it easy to interface with microcontrollers like Arduino, Raspberry Pi, ESP8266, and other development boards.
Features:
1. Specifically designed for ozone (O₃) gas detection
2. Dual Output: Analog (AO) and Digital (DO)
3. High sensitivity and fast response
4. Adjustable sensitivity via onboard potentiometer
5. Long lifespan with stable performance
6. Power indicator LED and digital output indicator LED
7. Compact and easy to install
8. Low power consumption
